Does double knit fabric pill?

As a seasoned supplier of double knit fabric, I am often asked whether this fabric pills. This question isn't just a casual query but one that holds significant importance for manufacturers, designers, and end - users alike. In this blog, we will delve into the science behind pilling, explore whether double knit fabric is prone to it, and discuss how to manage it.

Understanding Pilling

Pilling occurs when short or broken fibers on the fabric's surface become entangled and form small balls. These pills are typically the result of friction, which can be caused by normal wear and tear, such as rubbing against other surfaces, washing, or even the movement of the body when wearing the fabric.

The factors that contribute to pilling include the fiber type, fabric construction, and the finishing processes applied to the fabric. Natural fibers like cotton and wool have a relatively high tendency to pill because their fibers are more easily broken and can entangle. Synthetic fibers such as polyester are generally less likely to pill, but they can still form pills under certain conditions.

Double Knit Fabric: An Overview

Double knit fabric is a type of knitted fabric that is created by interlocking two layers of fabric together. This construction gives double knit fabric several advantages, such as increased durability, better drape, and a more substantial feel compared to single - knit fabrics.

There are different types of double knit fabrics, each with its own characteristics. For example, Plush Interlock Knit is known for its soft and plush texture, making it suitable for cozy clothing items. Underwear Interlock is designed specifically for underwear due to its smoothness and comfort against the skin. Wear Knit is a more general - purpose double knit fabric that can be used for a wide range of garments.

Does Double Knit Fabric Pill?

The answer to whether double knit fabric pills is not straightforward. It depends on several factors, starting with the fiber content.

Fiber Content

• Natural Fibers: If the double knit fabric is made primarily of natural fibers like cotton or wool, it is more likely to pill. Cotton fibers are relatively short and can break easily with friction. Wool fibers, on the other hand, have a natural crimp that allows them to entangle more readily. For example, a double knit wool sweater may start to show pills after a few wears, especially in areas that experience a lot of friction, such as the elbows and underarms.
• Synthetic Fibers: Double knit fabrics made from synthetic fibers like polyester or nylon are less likely to pill. These fibers are stronger and more resistant to breakage. A polyester double knit fabric used for sportswear can withstand a great deal of movement and washing without significant pilling.
• Blends: Many double knit fabrics are made from blends of natural and synthetic fibers. The blend ratio can significantly affect pilling. A fabric with a higher percentage of synthetic fibers will be more resistant to pilling than one with a higher percentage of natural fibers. For instance, a 60/40 cotton - polyester double knit fabric will pill less than a 90/10 cotton - polyester one.

Fabric Construction

The double knit construction itself can have an impact on pilling. The two - layer structure of double knit fabric provides more stability and protection for the fibers. This means that the fibers are less likely to be exposed to direct friction compared to single - knit fabrics. However, if the knitting tension is too loose, the fibers may be more easily displaced and form pills. A well - constructed double knit fabric with a proper knitting tension will be more resistant to pilling.

Finishing Processes

The finishing processes applied to the double knit fabric can also play a role in pilling. Some finishing treatments, such as singeing, can remove the loose fibers on the fabric surface, reducing the potential for pilling. Anti - pilling finishes can be applied to the fabric to make the fibers more resistant to entanglement. These finishes work by coating the fibers or altering their surface properties.

Managing Pilling in Double Knit Fabric

If you are using double knit fabric and want to minimize pilling, there are several steps you can take.

Care Instructions

Proper care is crucial in preventing pilling. When washing double knit fabric, use a gentle cycle and a mild detergent. Avoid using harsh chemicals or bleach, as they can damage the fibers and increase the likelihood of pilling. Turn the garment inside out before washing to reduce friction between the fabric and the washing machine drum.

When drying, air - drying is the best option. If you must use a dryer, use a low - heat setting. High heat can cause the fibers to shrink and become more prone to pilling.

Shaving and Depilling

If pills do form on the double knit fabric, you can use a fabric shaver or a depilling tool to remove them. These tools work by cutting off the pills from the fabric surface. Be careful when using these tools, as you don't want to damage the fabric.

Conclusion

In conclusion, whether double knit fabric pills depends on a variety of factors, including fiber content, fabric construction, and finishing processes. While double knit fabric generally has some advantages in terms of pilling resistance due to its two - layer structure, it is not completely immune.
